Hi Herkum,
After a un-&re-install of ActiveState 5.8.6, installing "Bundle-Perl-Critic" from the ActiveState ppm and then all specific packages it works now.
Originally I had indeed installed through cpan the "Bundle-Perl-Critic-IncludingOptionalDependencies".
Re-installing through ActiveState ppm the "Scalars::Util" always got stuck on the XS-part being skipped.
As of Perl 5.8.8 the MinGW GCC compiler is supported, older versions (such as 5.8.6) still need the Microsoft VC++ compiler (meaning licenses, etcetera).
There is the
tutorial how to achieve this with VC++. I'll test it out soon how to achieve this with VS2005. (The VS2005 is preferable to VS2003 due to VS2003 digital signature restrictions on compiled dll's.)
Many thanks for sharing your experiences!
Many thanks to all the other perlmonks who answered!
